windows to ubuntu convert... graphics problems.

[ricardino]

hi all, ive jus moved across from vista to ubuntu and ive been pretty impressed so far. the problem i have is that ubuntu wont remembermy screen resolution. My screens native resolution is 1280 x 800 an i can set it to this fine (ive already downloaded the correct driver with envyNG) however, whenever i restart my computer, it defaults back to 800 x 600.
any ideas?
thanks

im using ubuntu 9.04

First, do you have the package nvidia-settings installed? If not, install it.

sudo apt-get install nvidia-settings

You need to open the program with root privileges to save the configuration. Press ALT+F2 and type gksudo nvidia-settings

Change your resolution using that and save the configuration, and it should now stick.

i tried that, and restarted the machine... straight back to 800 x 600

It sounds like your driver module isn't loading. I'd hazard a guess it's as a result of using Envy. See if oyu can remove the driver using Envy and then after rebooting install it through System > Administration > Hardware Drivers. This is the preferred way to run the install.

You can check first if it's loaded. When you first boot up open a terminal and run

lsmod |grep nvidia

If it returns with an entry for the module, it's loaded otherwise it has failed to load.

Execute this

sudo lspci | grep -i vga

Post the contents of /etc/X11/xorg.conf file too.

ok the output of sudo lspci | grep -i vga

is

00:12.0 VGA compatible controller: nVidia Corporation GeForce 7000M (rev a2) (rev a2)

my xorg.conf is attached so you can have a look

thanks for the help
